Limestone is normally gray, but it might also be brown, yellow, or white. This mineral is a soft rock that you can easily scratch. It readily effervesces when mixed with any common acid. Limestones might vary in porosity and texture from coquina, a mixture of pieces of seashells cemented loosely by calcite.
